Application filed February 3, 1909.

To all whom it may concern Be it known that I, GEORGE C. BEIDLER, acitizen of the United States of America, residing at Oklahoma, in thecounty of Okla homa and State of Oklahoma, have invented certain new anduseful Improvements in Photographing and Developing Apparatus, of whichthe following is a specification.

This invention relates to a photographic and developing apparatus andparticularly to a reproducing machine by which drawings, printed andwritten documents, and records may be photographed.

An object of this invention is to produce a machine having a supply ofsensitized material, preferably of film, wound on a roll and adapted tobe unwound therefrom for the purpose of exposing the film to light, andin combination therewith, novel means for severing the film after it hasbeen exposed and developed.

A further object of the invention is to produce a machine of thecharacter noted having means for supplying film to be exposed and meansfor exposing said film as well as a novel receptacle for containingdeveloper in operative relation to means for exposing the film to lightand means for drawing the film through the receptacle.

Furthermore, an object of the invention is to provide a receptacle forthe developer and a drain pan associated with the receptacle, meansbeing provided for detachably holding the receptacle in the pan, the panand receptacle being incased but applied to the casing in such a waythat they may be removed for the purpose of repair or for the purpose ofcleaning the receptacles.

A further object of the invention is to produce a machine having a pancontaining fixing fluid, said pan being provided with a hood secured tothe casing; the casing being provided with a support for the pan, whichpan is in position to receive the severed developed films after they areprojected from the casing.

A'further object of this invention is to produce a novel cuttingmechanism in which astationary and a movable knife are emplo ed. thesaid movable knife having a vieldable pivot in order that it may adjustitself with relation to the stationary knife, means being also providedfor reciprocating the movable knife and exerting pressure thereonlaterally. r \Vith the foregoing and other objects in Specification ofLetters Patent.

view, the invention consists in the details of construction and in thearrangement and combination of parts to be hereinafter more fully setforth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specificatic-n, wherein likecharacters denote corresponding parts in the several views, in whichFigure 1, illustrates a side elevation of a photographing and developingapparatus embodying the invention; Fig. 2, illustrates a longitudinal,vertical sectional view through the developing tank and fixing pan, afragment of the bellows and magazine being shown; Fig. 3, illustrates aperspective view of a movable knife and the means for operating it; Fig.4-, illustrates a view in elevation of the side of the developer tank,partly broken away to show a drum, said view also illustrating thebracket for supporting the drum and the gearing for the feedrollers;'Fig.' illustrates a sectional view of the bellows showing theapplication of the ground glass thereto for the purpose of obtainingproper focus; Fig. 6, is a. detail view of the pivot for the movableknife, a fragment of said knife being shown in plan; Fig. 7, illustratesa view in elevation of the stationary and movable knives having meansconnected to the movable knives for imparting motion to one of the feedrollers; and Fig; 8, is a detail view of the ratchet wheel and partsoperating therewith. Fig. 9 is a detail sectional view of the feedingrollers, a tension device being shown in them. Fig. lOis a view inelevation of a bracket.

In these drawings A, denotes a bellows having a lens box B, and a lensC. The lens box is here shown as in position to operate in conjunctionwith a horizontally disposed supporting table (not shown) adapted tocontain copy for the material to be photographed, but as the means forsupporting the copy is an immaterial detail of construction. it is notillustrated. The bellows frame D, has a stud E, on each side adapted toengage a. hook D or the like by which the casing F. is held in operativerelation to ported by the base and is held in operative relation theretoby means of hooks H, which engage screws or studs 1.

The casing F, contains the magazine f, which is provided with bearingssuch as F for a core J, of a roll of sensitized material, and the saidsensitized material is drawn from the roll and through an opening Fbetween the casing and the bellows frame in order that the saidsensitized material may be exposed to light as it passes from themagazine to the developing tank. The casing, furthermore, has apartition K, therein forming the bottom of the magazine and saidpartition has a bracket L, secured to it near one end.

The side walls of the casing at their lower edges are provided withbrackets M, havin apertures Z to receive the journals N, or the drum 0,hence when the casing is removed from the base and bellows frame, thedrum is removed with it. Each bracket M, is provided with an elongatedbearing designed to receive the shaft P, of the upper feed roller Q. Theshaft P, is further mounted in an arm It, at each end, each arm P, beingpivotally mounted on a pin or stud n, projecting from the inner surfaceof a. bracket M. In order to hold the arm R, and the shaft P, normallydepressed, a spring T, has a looped portion encircling the stud S, andone extremity of said spring bears on the shaft P, whereas the otherextremity t, of said spring is anchored to the bracket M, hence it is bythis construction that the feed roller Q, is moved with relation to thefeed roller U, which feed roller U, is secured to a shaft to. The shaftP extends through one of the brackets M and the shaft u extends throughthe ends of the tank Y as shown in Fig. 1. The shafts P and u areprovided with gear wheels V and r, respectively, and the lower shaft u,projects beyond the side of the casing and has a crank XV, thereon, bywhich the shaft is rotated. The sensitized element, viz., paper or thelike, is shown at X, and it will be ob served that it passes around thedrum 0, and between the rollers Q and U, and that by turning the crankthe sensitized element is drawn from the magazine, past the ex posingchamber and into the tank Y.

The tank Y, is designed to contain developing fluid and is preferablyUshaped in cross section and is provided with a sup port Z, at each end,said Support having a foot 2, with an aperture to receive a stud .2,which projects from the bottom of the drip pan Z. The drip pan has adepending tube Z extending through an aperture in the J is provided forthe feet of the support of the tank remote from the bellows side of thecasing and as shown in Fig. 2, the upper e lge of the side wall of thetank lies under a bracket 8, secured to the bellows frame. in practice Iutilize two of these brackets 8, one near each end of the tank and theyact as braces to prevent movement of the tank, especially as the feet ofsaid tank are well anchored through the medium of the studs 2.

I have found it desirable to sever the sensitized element after it hasbeen exposed and developed and to deliver the severed portions of thesensitized elements to a pan 9, containing a fixing fluid. The wall ofthe casing is cut away to form an opening 10, through which thesensitized element is projected into the pan 9.

The cutting apparatus is mounted in conjunction with the bracket L,which has a sleeve 11, extending therefrom, the said sleeve being inline with an aperture formed in the bracket, which aperture and sleeveare designed to receive the pivot 12, on which the movable knife 13, ismounted and secured. lhe pivot 12, is provided with a collar 141-, and aspring 15, interposed be tween the collar and the end of the sleeve,which spring acts to hold the pivot normally projected rearwardly. andthe inner end of said pivot provided with a head 16, bearing against theknife .13, which is apcrtured to receive the pivot. The action of thespring 15, is, therefore, to draw the movable knife toward thestationary knife 17. which stationary knife is mounted on the lower endof the bracket L. The sleeve 11, is provided vith a diagonally disposedslot 18, and the pivot 12, has a pin 19, riding on the edge of thediagonally disposed slot 18. the camming action of which causes thepivot to more longitudinally in its bear ings against the action of thespring 15, in order that the movable knife may be permitted to clear theedge of the stationary knife.

In order to operate the movable knife, an arm 20, is applied to a recess21, of said morable knife near the end opposite the pivot and said arm20, projects from a collar 22, secured to a shank 23, of an oscillatinghandle El. and the shank is movable in one end of the casing. The outerextremity of the arm has an angular portion 20 which acts as a cam forthe movable knife and pre s it downward toward the stationary knife,while moving its cutting edge past the stationary knife, that is to saythe said arm will impart to the mova lateral pressure tending to forceit against the cutting edge of the statirmary knife, thus insuringproper action of the knives in operation. Owing to the lateral pressureimparted to oneend of the knife by the arm and the movement given to thepivot of the knife by the cam on the sleeve which permits the pivotedend to move slightly in a direction opposite to that im parted to theouter end of the knife by the arm, the knife has what might be termed aslight oscillatory motion with relation to the stationary knife and thestationary knife would act as a fulcrum for the pivoted knife. Unusualpressure is, therefore, applied to the contacting surfaces of the knivesand positive cutting action is insured. After a film has been severed bya complete stroke of the knife, the pivot of the knife is retracted bythe spring on the pivot as the knife swings upwardly under the influenceof the spring 25. The movable knife is held normally elevated throughthe medium of the spring 25, which is secured to a screw 26, in saidknife and to a screw 27, in the partition K, hence the said arm 20,operates the knife against the action of the said spring.

I have found in practice that when a sensitized element such as paperbecomes wet, it has a tendency to buckle and owing to the fact that themovable knife is pivoted at one end with relation to the stationaryknife, the space between the knives near the pivot of the movable knifeis rather restricted and hence, when the sensitized element buckles, itis apt to abut the movable knife when the feed rollers are manipulatedand when this occurs, the operation of the apparatus is impaired. Thereare several ways of obviating this difficulty, one of which is to havethe knives slightly longer than they are actually required to be forsevering the film in which event the restricted opening between the twoknives is removed from the edge of the sensitized element, and anotherway is'to impart to the sensitized element a slight projecting movementimmediately after a print has been cut therefrom, thus causing the endof the sensitized element to pass beyond thecutting edge of the knifefor any buckling thereafter would not affect the operation of theapparatus.

As a means for carrying into effect this latter idea for projecting theend of the sensitized element, I may extend the shaft P, in the oppositedirection to that having the crank and provide it with a ratchet wheel28. I then pivotally mount on the end of the shaft P, an arm 29,carrying a spring pressed dog 30, adapted to engage the teeth of theratchet wheel. A link 31, is pivotally connected to the arm 29, and saidlink is connected to a lever 33, pivoted on a bracket 32, which mayextend from the partition K, of the casing The inner end of the lever32, is connected through the me dium, of the link 33, with an ear 34, onthe knife 35. In the form shown in Fig. 7, the knife 35, is movable. andacts in con unction with the stationary knife 36. In this form,

an arm 37, similar to the arm 20, is used for the purpose of actuatingthe movable knife.

As shown in Fig. 5, the apparatus is focused by applying to the bellowsframe D, having the bracket 8, a ground glass 39, in a suitable frame38, and in order to apply the ground glass frame, it is necessary todisplace the removable section of the casing.

The operation of the apparatus will be as follows: The proper focushaving been attained and the casing having been applied to the base, thefeed roller P, removed with the casing will be restored to its operativerelation to the feed roller U. The sensitized element will then be inposition between the two rollers and when motion is communicated to thelower roller through the medium of the crank, the said rollers will bedriven in unison through the medium of the gearing V and 1), thus apositive feeding action will result and as the springs I, press the tworollers together, sufficient friction is produced between the rollersand the sensitized element to insure positive feeding action of the saidsensitized element. After the sensitized element has been exposed anddrawn into the developing tank and is acted on by a chemical therein, itis projected between the knives and through the opening in the casing tothe pan 9. lVhen a given length of the sensitized element has passedbetween the knives, the knife operating mechanism is pressed so that thesensitized element is severed, the severed length finding its way intothe pan 9, containing the fixing fluid. In order to prevent light fromgaining access to the pan 9, the said pan is provided with a hood 39,which may be of any well known con struction, but it is preferably ofthe construction shown herein and specifically claimed in a companionapplication filed by me July 10, 1908, Serial Number 442,877, and assaid hood is fully described in said application, it will not bedescribed in detail here.

\Vhen the apparatus shown in Fig. 7, is employed in connection with theknives, it follows that when the pivoted knife descends, the lever 32,will be oscillated on its pivot and the arm 29, will be moved to carrythe dog 30, into engagement with teeth in advance of the one engaged byit as shown in Fig. 8. After the knifehas descended the full stroke andthe knife operating mechanism is released, the spring 25, will elevatethe knife and oscillate the lever 32, in order to carry the arm 29, backto the position in which it is shown in Fig. 7, and with the return ofthe arm to said position, the ratchet wheel 28, will be partiallyrotated, and hence the shaft P, will partially rotate and communicatemotion to the feed roller thereof and to the companion feed rolleracting in conjunction with it, and thus the edge of the sensitizedelement will be carried beyond the knife and the sensitized element willbe free of any obstruction when power is again applied to the feedrollers.

The casing has an opening in front in communication with the bellows andafter the sensitized element comes to rest in the opening, it may beexposed to, light. The opening is also provided with a guide which isattached to the side edges of the opening, and the said walls of theopening are further provided with slots to receive a dark slide.
